How do I keep my arms straight while bowling?

Techniques to Keep Your Swing on the Straight and Narrow Place the ball into the swing in the direction of your intended ball path. Maintain a stable hand position as the ball goes into the backswing. Tilt your bowling side shoulder in the setup to begin creating space for the ball to swing straight by your body.

How do you bowl off spin without chucking?

Release the ball at the top of your rotation. As you’re swinging your bowling arm and turning your wrist and index finger, open your hand slightly to release the ball. Wait until the ball is at the top part of your throw so it goes where you aim. If you release the ball too early, it will fly straight up into the air.
